Abstract

Measurements of electrical and thermal transport coefficients in the antiferromagnetic alloy Cr_99.94Al_0.06 reveal an anomaly near the Néel temperature T_N. Temperature derivatives of the electrical resistivity and thermo-power are analysed and are shown to be proportional to each other above and below T_N in the reduced temperature range 6 × 10^-2 ≥|t|≥ 4 × 10^-4. This is consistent with the theoretical prediction of a universal critical behaviour of all transport coefficients.
